If I have a lot of tickets without estimated time, it would be nice to bulk edit estimated times.(Or is that possible? - I didn't find that)

For example select all the ticket where I want to estimate time to, right click, menu - "estimate time (for selected tickets)".If there would be a list with selected ticket and an input fieldfor each time I want to estimate - that would be great.

One way to make the UI simpler here would be to define a list of preset times, which could be directly selected from the context menu. ISTM that if you are doing bulk updates you're probably doing an order-of-magnitude estimate anyway, so high precision isn't really required.

Something logarithmic, like 30m/1h/2h/4h/1d/2d/4d/1w, would give a value never more than 40% or so from any actual estimate, which as a quick cut seems more than sufficient. Allowing the list to be custom defined would obviously be more flexible, though.

I specifically identify new issues by their lack of an estimate - however where 100' of entries were added as subtasks of a complex ISO compliance effort I would like to be able to just give each the same nominal estimated time for now. Strangely this is not possible!

@Ewan : Bulk edit of estimated times is possible through the right click menu over the check column of lists of issues.> Check all items you want to update (click the header line check icon to check all)> right click over that column-> Choose the very first item (Change, with a pen icon)You will reach a page where you can set an Estimated time.Note that you can change the number of issues listed in a single page in the Administration options.

Giving various values for items in the list and saving all when finished is not possible, though, and this is the purpose of this request.
